[RFC PATCH 08/12] weston-init: correctly start under systemd

["Alexander Kanavin" <alex.kanavin@gmail.com>]

Several issues are addressed:
1. weston requires pam when starting under systemd
2. systemd was attempting to launch weston twice (from
sysvinit script and from systemd unit file) which caused confusion
and errors.
3. runtime test should stop/start weston via systemd only if systemd
actually controls system startup, not merely when systemd is present.
